Abstract (en)

A rotator for a machine for machining metal sheets comprises metal sheet gripping and rotating means (2, 3, 5-9) for positioning a metal sheet (4) in a plurality of allowed angle positions around an axis perpendicular to it. Centering and clamping means (10-18; 10, 11, 13, 40-46; 30-39) for said sheet (4) are provided to center and clamp the sheet in any one of said angle positions. The centering and clamping means (10-18; 10, 11, 13, 40-46; 30-39) include a cog wheel (10; 30), that is rotatable fixedly to said sheet (4) and comprises a number of teeth equal to the number of said allowed angle positions, means (12; 40; 32) for engagement with said cog wheel (10; 30) that are provided with a toothing complementary to, and suitable to engage with at least one part of, the teeth of said cog wheel (10; 30) in order to determine precise centering and stable clamping of the metal sheet (4) in any one of the allowed angle positions. <IMAGE>
